1 Claim. (01. 189-342) Theinvention relates to a window, andmore especially to a window having upper and lower sash hr, aremji vable sash frame.

,The primary object of the invention is the provision of a window of this character, wherein the sashes, both upper and lower, are slidably fitted, for vertical sliding movements, in a horizontally swinging frame so that the window can be opened without sliding the sashes to open position, as is customary, the fram being latched or fastened securely when in a fully closed position, and the sashes may be raised and lowered,respectively, for ventilating purposes, as is common practice.

Another object of the invention is the provision of'a window of this character, wherein it can be constructed from sheet metal, and such window in its entirety eanbe removed at will, thus permitting the glass panels to be readily and easily cleaned with dispatch, the window being of novel construction and is unique in the assembly of its component parts.

A further object of the invention is the provision of a window of this character, wherein it is devoid of a complicated set-up, and i possessed of few parts, thus economical in repairs and replacements, the parts being readily accessible.

A still further object of the invention is the provision of a window of this character, which is simple in construction, thoroughly reliable and eflicient in operation, strong, durable, conveniently handled, readily installed and removed, and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction,

combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1 is an inside elevation of the window constructed in accordance with the invention;

Figure 2 is an outside elevation of the window, showing the screen partly broken away in position;

Figure 3 is the same as Figure l, with the win- 1 dow removed and the screen in place;

Figure 4 is an elevational View partly in section, showing the sash raising and lowering mechanism;

Figure 5 is a sectional view taken on the line 5-5 of Figure 1, looking in the direction of theof Figure 4, looking in the direction of the arrows;

Figure 7 is a topplan view partly in section, with the window partly open and 7 Figure 8 is a sectional view on the line 858 of; Figure 1. 7 v

Simila reference characters indicate correspending parts throughout the several views in the drawings.

Referring to the drawings in detail, th window constituting the present invention comprises a permanent window opening frame structure. I 0 having the interior head piece l2, vertical side pieces i hthe base or bottom sill piece Hiand. apron [8 respectively formed integral and removably secured to the window by hanger 20 engaging theupper edge of the frame I 0 and the longi tudinal flange 22 on the rear longitudinal edge of the sill is engaging the upwardly extending U-shap-ed flange 24 formed on the rear edge of the exterior sill 26, having the exterior apron 28 on which is formed at the opposite ends thereof, the upstanding flange 30. Within the center vacancy of the frame structure is located a removable and horizontally swingable sash carrying frame 32,1ts vertical side pieces 34 being fitted with parting and guide strips 36 and 38 respectivelyfor upper and lower sliding sashes All and 42, both fitted with glass panels 45 as usual.

The frame 52 near one long side edge of the same has fitted therein, vertically disposed upper and lower turning arbors i6 and 48 respectively, the upper arbor 46 also being a sliding latch bolt, operated by knob 59, while the lower arbor is a fixed release pivot. The upper arbor 4B is adapted for engagement in a keeper in the frame 19, while the lower arbor 48 is releasably fitted in socket therefor, in the frame It, and these arbors when so engaged permit the frame 32' to swing inwardly in a horizontal direction with respect to the wall frame structure I0 or unlatched and released or removed therefrom, optionally.

The upper sash 40 is raised and lowered by cable 52, and such cable is trained overv guide pulleys 5d properly located in the frame 32 at the top thereof and pulley at the bottom thereof. The lower sash A52 is raised and lowered by cable 53, and such cable is also trained over guide pulleys 54 and 55- respectively. The pulleys 54 are rotatably mounted on shafts 51 while the pulley 55 is rotatably mounted on shaft 59. The cable 52 for the upper sash 4B is operated from a rotating shaft 56, while the cable 53 for the lower sash 42 is operated from a rotating shaft 58, both being turned by hand with a hand key having socketed engagement therewith. interpolated in the cables 52 and 53 respectively for the tightening thereof, are the turnbuckles 62 and 63 re- This frame 32 is effected weatherproof within the structure If! in any suitable manner, and the lower sash 42 is provided with a, depending flange '66 for the weatherproofing' thereof, along the bottom edge at its engagement with the frame It]. should be obvious, while the sashes can be raised or lowered for ventilating purposes with ease and dispatch.

There has thus been provided, a window which may be manufactured and adjusted for perfect operation at the factory, a window that permits unit installation which can. be counterbalanced for perfect operation since the cable 52 is welded to the upper sash 40 on the right side at" the top thereof as at 68, and the left side of the bottom of. the upper sash 40 as at 10. The cable 53 is welded to the lower sash 42 on the right side at the top thereof as at 69 and the left side of the bottom of the lower sash 42 as at I l. The sashes being crank operated, are easily operated in places where conventional sashes are operated 30 with difficulty; these sashes provide a window which eliminates weights and other counterbalancing equipment; that is simple in construction,

operation and installation, easily accessible for adjustments when needed, fireproof, rattle-proof and waterand weatherproof at the factory, and one which will provide an economical installation.

The frame 32 can be opened or closed, as

4 It is believed that the operation and advantages of the invention will be apparent to those skilled in the art, and it is to be understood that changes may be resorted to in the minor details of construction, arrangement and combination of parts provided they fall within the spirit of the invention and the scope of the appended claim.

What is claimed is:

In a metal window frame having an outer wall opening frame, the improvement comprising sliding upper and lower sashes arranged within the frame, guide. pulleys arranged in the opposite upper corners of said frame, a guide pulley positioned in one lower corner of said frame, cables connected to each of said sashes, a first cable connected to the upper end of said upper sash and the lower end of said upper sash, a second cable connected to the upper end of said lower sash and to the lower end of said lower sash, said cables being trained over said pulleys, tightening means in said cables, a rotating shaft for each cable for the raising and lowering of each cable and their respective upper and lower sashes and means removably connected to said rotating shafts for the manual rotation thereof.
